| Outline of Final Research Achievements |
Impact analysis of renewable energy generation installations requires computational simulations. Typical modeling of power systems in these simulations is achieved by discretizing the time domain which inherently lies in continuous domain. Typically, the constant time interval such as one second or thirty minutes is applied in the discretization process. Applying shorter time intervals would improve the accuracy of modeling, however, it could terribly elongate the computation time. This research developed the variable discretization technique, which applies different time intervals considering the necessity of analysis. The developed method was applied in battery sizing and unit commitment (UC) problems. Especially, for the UC, the proposed method succeeded in reducing the computation time by 30% of conventional methods.
